Qinji QJDZT Vertical Suction Vibration Test System

Overview

The Qinji QJDZT Vertical Suction Vibration Test System is an electromechanically driven sinusoidal vibration shaker engineered for laboratory- and production-line-based environmental simulation of vertical mechanical stress. It operates on the principle of electromagnetic force generation via voice-coil actuator architecture, producing controlled, repeatable vertical (Y-axis) oscillatory motion to replicate transport-induced shock and resonant excitation encountered during packaging, logistics, and field deployment. Unlike broadband random or transient shock systems, the QJDZT specializes in deterministic sinusoidal profiling—enabling precise frequency sweeps, resonance dwell testing, and fatigue evaluation at fixed or swept frequencies between 0.5 Hz and 600 Hz. Its design targets functional verification, structural integrity assessment, and early-life failure detection in electronic assemblies, automotive components, medical devices, and consumer goods prior to market release.

Key Features

• Electromagnetic actuator with high-force-to-mass ratio and low harmonic distortion (<2.5% THD at full stroke), ensuring waveform fidelity across the operational bandwidth.
• Dual-channel output architecture: two independently controllable vibration drivers allow parallel testing of dissimilar samples or synchronized multi-point excitation on a single fixture.
• Programmable control firmware supporting three standardized test profiles—P-Series (performance qualification), W-Series (warehouse handling simulation), and T-Series (transportation cycle emulation)—each preconfigured with amplitude, dwell time, sweep rate, and stop criteria per ISO 10326-1 Annex A.
• Real-time frequency stability of ±0.1% maintained via closed-loop digital signal processing (DSP) feedback from integrated accelerometer transducers mounted on the moving table.
• Robust cast-iron base and reinforced aluminum table structure (load capacity: 50 kg static, 25 kg dynamic at 600 Hz) minimize parasitic modes and support rigid fixture integration.
• Front-panel LCD interface with USB and Ethernet connectivity enables local setup and remote monitoring without proprietary software dependency.

Sample Compatibility & Compliance

The QJDZT accommodates test specimens up to 300 mm × 300 mm × 150 mm (L×W×H) on its 350 mm × 350 mm platform. Fixturing options include threaded inserts (M6), T-slots (12 mm), and optional vacuum suction plates for non-permanent mounting of flat-bottomed enclosures or PCB subassemblies. The system conforms to the mechanical vibration test requirements of IEC 60068-2-6 (sinusoidal vibration), ISO 10326-1 (vibration testing of packaged products), and GB/T 2423.10 (Chinese national standard equivalent). While not certified as GMP-compliant hardware, its deterministic control architecture supports audit-ready test documentation when paired with external data acquisition systems compliant with FDA 21 CFR Part 11 for electronic records and signatures.

Software & Data Management

The QJDZT operates natively via embedded firmware with no mandatory PC software dependency. However, optional Qinji VTS Control Suite (Windows 10/11 compatible) provides extended capabilities including test sequence scripting, real-time FFT spectral visualization, automated report generation (PDF/CSV), and GLP-compliant audit trails—including user login timestamps, parameter change logs, and test completion certificates with digital signature fields. All exported datasets include metadata headers specifying test ID, operator, date/time, frequency setpoint, acceleration amplitude (m/s²), displacement (mm), and duration—ensuring traceability for internal quality reviews or third-party certification submissions.

Applications

• Resonance search and dwell testing to identify critical natural frequencies in printed circuit board assemblies and housing structures.
• Transport simulation per ISTA 3A or ASTM D999 protocols using predefined P/W/T-series waveforms to assess package integrity and product functionality after simulated shipment.
• Accelerated life testing of solder joints, connectors, and MEMS components under controlled vertical cyclic loading.
• Verification of mounting bracket rigidity and fastener retention in automotive infotainment modules and industrial control panels.
• Evaluation of display module adhesion strength and touch sensor calibration stability under sustained low-frequency vibration (e.g., 5–20 Hz engine harmonics).

FAQ

Is the QJDZT capable of horizontal (X- or Z-axis) vibration testing?
No. The QJDZT is strictly a single-axis vertical (Y-axis) shaker. Horizontal motion requires separate equipment or a triaxial shaker system.
What is the maximum displacement amplitude at 10 Hz?
At 10 Hz, the system delivers ±5.0 mm peak-to-peak displacement with rated load (25 kg). Displacement decreases inversely with frequency squared above 50 Hz per actuator physics constraints.
Does the system include calibration certification?
Yes—a NIST-traceable accelerometer calibration certificate (valid for 12 months) is supplied with each unit. Annual recalibration services are available through authorized Qinji service centers in Asia and Europe.
Can test profiles be exported/imported between instruments?
Yes. Profile files (.qvt format) are portable across QJDZT units and compatible with Qinji VTS Control Suite v2.4 or later.
Is vacuum suction integrated or optional?
Vacuum-assisted sample retention is an optional add-on kit (Part No. QJDZT-VAC-01), including a 24 V DC vacuum pump, pressure regulator, and manifold-equipped table insert.
